Questions and Answers

Do you have you a question about the Mercusys Halo S12(3-pack) AC1200 Whole Home Mesh Wi-Fi System?

Q: Hi there. As are many of us, I am now working from home and my new office is our little 3rd bedroom. I currently have a ethernet cable from our main router box downstairs directly into my laptop port unit but am still getting dips in the wifi/vpn, especially when I have to close the door. I also find that my small personal tablet (for when I'm watching Netflix) is always either buffering or having problems connecting with the wifi when upstairs. Do you think this Mesh kit will help? and if so, is it easy to set up as I'm not a very techy person. thanks

What a great wee bit of kit. Went from getting access to 5mbs of our 80mbs in the kitchen without to about 60 per room... Just a wee non hideous white box set tying in the corner of the room

no trouble to set up (unless randomly you do not have an all in one router), works as intended no issues at all.

This Mercusys Halo S12 pack of 3 units is a game changer for my household. We have a number of devices at home and it shows no problems connecting them all. Guests have no problems connecting either. We have Wi-Fi reaching out to all corners of the house and also in the garden now! which is absolutely essential I thought during the lockdown summer period. Probably the best value Wi-Fi Mesh product out there. Well done Mercusys. Sara

Great product. Bought it to fix weak WiFi signal in my conservatory and upstairs sons bedroom. It is doing this very well and we have some spare WiFi coming into garden too. Very affordable for a 3 pack solution. Would highly recommend.
